Joint Power Allocation at the Base Station and the Relay for Untrusted Relay Cooperation OFDMA Network
The secure communication that multiple OFDMA-based cell-edge mobile stations (MS) can only transmit confidential messages to base station (BS) through an untrusted intermediate relay (UR) is discussed. Specifically, with the destination-based jamming (DBJ) scheme and fixed MS transmission power assu...
